Sound levels
(see note 1)
Equivalent sound pressure level at the user’s ear,
measured according to ANSI B175.3--1997, dB(A),
min/max: 94/97
Vibration levels
Vibration levels at handles, measured according to
ANSIB175.3--1997, m/s
2
At idle, left/right handles: 3/5
At max. speed, left/right handles: 9/8
NOTE! This spark ignition system complies with the Canadian standard ICES--002.
Note 1: Equivalent sound pressure level is calculated as the time-weighted energy total for
sound pressure levels under various working conditions with the following time distribution:
1/2 idling and 1/2 max speed.
NOTE! The noise pressure level at operator’s ear and vibrations on the handles are mea-
sured with all the approved cutting attachments for the machine. The table indicates the
measured values.
